For several months I'm using Linux Clear kernel built from AUR. I like its balance between performance and UI responsiveness and found that the system works more stable than arch/zen/ck kernels.
But found an issue: Optimus Manager can't switch between Intel and nVidia graphics.
When I attempting to switch, it just restarts X session under Intel graphic processor.
Any other kernels do not face such problems.
My video card: nVidia GM108M / GeForce 840M
Processor: Core i5-4210U
I use only X11.

Moving to AUR Issues...

Aur lists 2 optimus-manager packages building stable and 2 building git versions .
Which of the 4 are you using ?
Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
(A works at time B) && (time C > time B ) ≠ (A works at time C)

optimus-manager
optimus-manager-qt
Anyway, the result is the same.

The nouveau kernel module is included in archlinux kernels.
Try blacklisting nouveau .

Blacklisted nouveau and removed nouveau from the kernel. The message is disappeared, but the problem still exists.
I suppose that an issue is on kernel site.
